The trailing semi-colon feels a bit odd, doesn't it?

(Also, when using a semi-colon, wouldn't the next word -- Function
and Variable here -- be lower-case?)


Yes, I'll fix these next time I change the file.

 Full support for https://www.cilkplus.org/";>Cilk Plus
 	has been added to the GCC compiler. Cilk Plus is an extension to
 	the C and C++ languages to support data and task parallelism.
+New preprocessor constructs, __has_include
+and __has_include_next, to test the availability of headers
+have been added.
+This demonstrates a way to include the header 
+only if it is available:
+
+#ifdef __has_include
+#  if __has_include()
+#include 
+#define have_optional 1
+#  elif __has_include()
+#include 
+#define have_optional 1
+#define experimental_optional
+#  else
+#define have_optional 0
+#  endif
+#endif
+
+The header search paths for __has_include_next
+and __has_include_next are equivalent to those
+of the standard directive #include
+and the extension #include_next respectively.
